Version-2.0.0

Release Date : May 2026

Major Features

Quadrant Folding – Synthetic Evaluation & Optimization Overhaul

  • Synthetic Gaussian data generation for quantitative evaluation of background subtraction quality

  • Full evaluation metric suite: MSE against synthetic data, equator metrics, symmetry score, and composite loss; metrics exported to background_metrics.csv

  • Evaluation baseline persistence: optionally fix a reference baseline image across the dataset for consistent comparisons

  • “Optimize each image” mode: run the background parameter search independently per image rather than reusing the folder-level best configuration

  • Optimization timeout feature: cap the per-image search time to prevent runaway computations

  • Background search utilities extended with process_file_with_timeout, full evaluate_loss pipeline, and improved parameter range handling

  • Synthetic parameters and evaluation baseline stored in the processing cache for reproducibility

  • persist_evaluation_baseline and optimize_each_image checkboxes added to the QF settings bindings

Quadrant Folding – CSV and Headless Consistency

  • QF_CSVManager extended with versioning and timestamp columns (version, date) in summary.csv

  • New columns in summary.csv: blank_enabled, mask_enabled, blank_weight, detector, lambda_sdd—sourced from SettingsManager/ImageData so GUI and headless report identical values

  • ROI preferences (fixed_roi_w, fixed_roi_h) mapped to canonical CSV columns

  • Headless QuadrantFoldingh now applies blank and mask preprocessing settings from SettingsManager, matching GUI behavior

  • processing_flags propagated from QuadrantFolder through to QF_CSVManager

  • Background metrics CSV upserted into the processing info for headless consistency

  • Transition background parameters added to evaluation baseline handling

Documentation Overhaul

  • All major module docs refreshed: Equator, Quadrant Folding, Projection Traces, X-Ray Viewer, Add Intensities, Scanning Diffraction, Total Diffracted Intensity

  • New dedicated Quadrant Folding – Background Subtraction reference page with manual and automated methods, settings descriptions, and worked examples

  • Utilities section reorganised; DDF Processor and Convert Rectangle Image to Square Images entries added

  • Deprecated/outdated doc files removed; broken links updated to .md extension

  • Common Settings page expanded to cover calibration workflow

.. note:: Version 2.0.0 is a major release. This version has been tested on Python 3.10 on Ubuntu 22.04.
